Struct Registry 

pub struct Registry {
    pub schema_hash: String,
    pub kinds: Vec<Kind>,
    pub queries: Vec<QueryDecl>,
    pub roles: Vec<RoleDecl>,
}

Everything the engine may know about a KB’s shapes.

Fields

schema_hash: String

Hash of the schema crate’s source — accept checks freshness against it.

kinds: Vec<Kind>

queries: Vec<QueryDecl>

Schema-authored analytical queries. The schema constructs these through the typed builder; this committed representation is backend-neutral and can be rendered by the web UI without parsing Rust.

roles: Vec<RoleDecl>

This KB’s role vocabulary — flat, declared once, adoptable by any kind (a Field’s role names one). Universal for THIS KB, invisible to every other: the KB’s words, mapped onto engine affordances.

Implementations

impl Registry

pub fn role(&self, name: &str) -> Option<&RoleDecl>

pub fn binds(&self, field: &Field) -> Option<Affordance>

The engine affordance a field’s adopted role binds, if any.

pub fn affordance_field<'a>( &self, kind: &'a Kind, a: Affordance, ) -> Option<&'a Field>

The field of kind bound to affordance, if any.

pub fn coherence_errors(&self) -> Vec<String>

STRICT role coherence — an incoherent mapping makes the registry meaningless, so these are hard errors wherever a registry is loaded or generated: every adopted role is declared; the field’s shape fits the affordance (Title = str, Timeline = date, Badge = enum); a Badge role’s shared variants match the adopting field’s enum EXACTLY. A kind wanting different vocabulary declares its own enum field and simply doesn’t adopt the role.

pub fn query_errors(&self) -> Vec<String>

Bind every emitted query back against this registry. Typed Rust catches mistakes at the authoring call site; this second gate protects the serialized artifact from drift or hand edits.

Trait Implementations

impl Clone for Registry

fn clone(&self) -> Registry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Registry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Registry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Registry

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
